By closely reexamining and mathematically reformulating the basic experimental laws of electrodynamics, the equations governing the electromagnetic fields felt by moving bodies are established. These equations are the generally mathematical expressions of the laws of electrodynamics, the Galilean principle of relativity shown to apply to them. The Maxwell equations, valid only for the electromagnetic field felt by stationary bodies, are only a special form of these equations. Because the electromagnetic fields felt by different bodies in motion relative to each other are different, no matter what the origin of these fields may be, these equations consistently show that every radio signal travels relatively to its particular receiver, the relative velocity of propagation in the absence of matter always equal to c, independent of the state of motion of the receiver as well as the emitting body.
